EMIL BARTHELMESS, or NEUSS, GERMANY;

PACKING-MACHINE.

SEECIFIGATION forming part of Letters Patent No. 686,195, dated November5, 1901.

Application filed October 29, 1900. Serial No. 34,849. (No model.)

To all whom it may concern:

Be it known that I, EMIL BARTHELMESS, asubject of the German Emperor,residing at Neuss-outhe-Rhine,Germany,have invented a certain new anduseful Improved Packing- Machine, of which the following is aspecification.

This invention relates to packing-machines; and the objects andadvantages thereof will be set forth in the accompanying specificationand the novel features pointed outin the appended claims.

Referring to the drawings forming a part of this specification, Figure 1is a front elevation of a packing-machine involving my improvements,showing barrels on the supporting-tables in section. Fig. 2 is averticalcentral section of part of the counterbalancing mechanism; and Figs.3and 4: are transverse sections on the lines 3 3 and 4 4:, respectively,Fig. 2.

Like characters refer to like parts in all the figures of the drawings.

The framework is denoted in a general way by A, and it supports ahopper, as 5, having the diverging spouts 6, the lower portions of whichare vertical and contain the feed screws or worms 7, which alternatelyforce the material into receptacles, as 8, on the floors of carriages orelevators 9. These elevators are adapted to sustain the receptacles inposition to receive charges of material from the spouts 6, the materialbeing forced into such receptacles and packed therein by the rotaryfeedscrews 7 at the lower ends of the upright shafts 10, the rotation ofthe shafts, and hence of the feed screws, being automatically stopped,as will hereinafter appear. When said feed-screws are at rest, they,being of the same diameter as the interior of the spouts 6, act aseffective valves to prevent the accidental escape of material from thespouts. The elevators are connected with weights, as 12, which when theelevators support empty casks or barrels are adapted to raise the sameto bring such casks or barrels into their charge-receiving positions, itbeing understood that the elevators rise and fall in unison and inalternation, the descent thereof being secured by the weight of thefilled barrels 8. The manner of transmitting the effect of these weights12 to the elevators will be hereinafter set forth and also means forcontrolling the descent of the elevators, so

.that this motion will not be too rapid.

The shafts 1O carry bevel-gears 13 at their upper ends, meshing withbevel-gears 14 and 14 on the horizontal shaft 15. The shaft 15 supportsat its outer end the three pulleys 16, 17, and 18, the last two beingcarried directly on the shaft, the pulley 17 being an idler, while thepulley 18 is keyed or otherwise fixed to said shaft. The bevel-pinion 14is fixed to the shaft 15, while the bevel-pinion 14 and pulley 16 aresecured to a sleeve 19, loose on the shaft. A belt, as 20, is shiftablefrom one pulley to another, and when it is on the pulley 16 theright-hand feed-screw 7, through the intermediate connections, will beoperated, and when it is shipped to the pulley 18 the feed-screw 7 atthe left will be rotated, and these actions will alternate while themachine is in operation.

The weights 12 are suspended from cables or bands, as 22, connected insome convenient manner with the respective elevators, so as to raise thesame at proper points in the operation, and said bands are passed oversuitably-positioned guide-rollers 23 on the framework A and also aroundgrooved rollers 24:. There are six of these rollers shown, they beingarranged in sets of three, keyed, respectively, .to sleeves, as 25,loose on the shaft 26, located below the shaft 15. These sleeves alsocarry fixed wheels or disks, as 27 and 28, respectively, and they rotatein unison with the respective elevators.

The belt 20 is moved along the pulleys 16, 17, and 18 automatically by ashipper, as 30, suitably carried by the framework A, for horizontalreciprocation, and it has at one end the usual belt-engaging fingers,between which the belt 20 travels. This belt-shipper is moved back andforth by means of pins or tappets 31 on the outer faces of the wheels 27and 28, which engage the upper oppositelyinclined faces of a lever 32,pivoted to a lever 33, vibratory upon the framework and connected withthe belt-shipper by a pin-and-slot joint, and the parts are so arrangedthat the belt 20 will be put upon the pulley 16 when the barrel 8 at theright is in position to receive a charge of material, and the sameoperation is repeated when the barrel or cask at the left is in positionto receive its charge, and these operations will alternate so long asthe shaft is in motion and material is supplied to the apparatus.

The wheels 27 and 28 have ratchet-wheels, as and 36, rotative therewith(see Figs. 2, 3, and 4) and formed on the hub of the brakewheel 15 andengaged by pawls, as 37 and 38, pivoted to the respective wheels, thepoints of the pawls being held in their effective positions by coiledsprings, as 35, surrounding the pins 36, pivoted to the tails of thepawls and passing freely through guide-lugs 37 on the wheels 27 and 28.

The brake-wheel15 is surrounded bya friction-strap 14 of some usualkind, by which its rotation can be controlled.

On the ascent of the tables the pawls run idly over the teeth of theratchet-wheels, but their descent is governed by the pawls en gaging theratchet. During the descent of the right-hand elevator 9, and justbefore the cask 8 thereon is filled, the tail of the pawl 37 will strikethe fixed stop 40 on the framework, thereby lifting the point of thepawl out of engagement with the ratchet, so that the elevator isautomatically released and can descend to the limit of its movement topermit the removal of the filled barrel,and the same operation will besubsequently repeated by the pawl 38 striking the fixed abutment 41.

The feed-screws 7, it will be understood, are alternately stopped andstarted, and an alternate operation follows with respect to theelevators 9, one descending with a filled barrel or like receptaclewhile the other is ascending with an empty barrel.

On the reverse rotation of the wheels 27 and 28 the straightfaces 43 ofcams 43 and 44, carried by the wheels 27 and .28, are adapted to strikeagainst the branches of a bifurcated bolt on the framework. During thedescent of, say, the elevator at the right the working face of the cam43 will strike the righthand branch of the bifurcated bolt 45 and forcethe same downward to release the cam 44, and hence the wheel 28, so thatthe elevator on the right can be lifted by its weight 12, and the sameoperation will be repeated by face 44 of the other cam 44.

The bolt 45 is held up by a coiled spring 46, surrounding the same, andwhich when the bolt is forced down by the cams alternately is placedunder compression.

Having described the invention, I claim 1. In a packing apparatus,elevators, a hopper having diverging spouts, feed-screws operative inthe respective spouts,a plurality of pulleys, connections between thefeedscrews and pulleys for operating the former, a belt-shipper, twoconnected levers one carried by the other, and the latter supported foroscillation by the framework and being connected with the belt-shipper,a pair of wheels connected with and operated by the elevators, and meanson the wheel for engaging one of said levers.

2. In a packing apparatus, elevators, a hopper having diverging spouts,feed-screws operative in the respective spouts, a plurality of pulleys,connections between the feedscrews and pulleys for operating the former,

a belt-shipper, two connected levers one carried by the other, and thelatter being supported for oscillation by the framework and beingconnected with the belt-shipper, a pair of wheels connected with andoperated by the elevators, means on the wheel for engaging one of saidlevers, a brake-Wheel having ratchet-wheels connected therewith, andspring-actuated pawls carried by said pair of wheels for engaging theratchet-wheels.

3. In a packing apparatus, elevators, ahopper having diverging spouts,feed-screws operative in the respective spouts, a plurality of pulleys,connections between the feed screws and pulleys for operating theformer, a belt-shipper, two connected levers one carried by the other,and the latter supported for oscillation upon the framework and beingconnected with the belt-shipper, a pair of wheels connected with andoperated by the elevators, means on the wheel for engaging one of saidlevers, cams carried by said pair of wheels, and a spring-actuatedlever, having a bifurcation, the branches of which are adapted to beengaged by said cams.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
